Changes in portfolios of shrimp harvesters

Entry and exit

Post closure, shrimp (css, csc), lobster-apprentice under 18 (lau), and elver dip net fyke 1 (e6) are replaced by menhaden (menc, menr), spat, and aquaculture, all of which are new license categories and don’t necessarily represent a shift in fisheries.

The proportion of licenses held by shrimpers didn’t appear to change dramatically by those who chose to continue in fisheries. Lobster was still the dominant target species by these harvesters.
